This is not a simple “resizer” tool, it does not give different resize algorithm (lanczos, spline or whatsoever), but it manipulates the image in different ways – it’s more a “remove unwanted objects” program :

Areas marked with green marker will remain unchanged as long as possible during resizing.
Areas marked with red marker will be removed first when resizing to smaller size and multiplied first when resizing to a larger size.

iResizer now supporting transparency (and it does it perfectly) is no big news for you if you use it on your photos only, but for those who go for graphics and working with layers, it is a BIIG improvement. Hopefully its sister software InPaint will follow soon. Nothing about it on TeoreX site at first glance. I can understand why developers prefer to keep their changelogs very private when they do nothing else than fix bugs, but why not advertise real enhancements?!

I already said that I would prefer the red brush for areas that should not be changed and the green one for areas that can be, instead of the opposite, but that's me :)

I repeat also what I said a year ago (and, actually, it doesn't apply to this giveaway only): do not trust what GOTD pop up or the "About" says, you are not sure that your program is registered until you have successfully saved a modified image. If iResizer asks you to register before saving, rerun Activate.exe (before the end of the giveaway!)

@ MikeR: You are definitely right about the limits of iResizer's "intelligence", but I do not expect any computer program to be intelligent enough (i.e. as intelligent as me) to process "any and every image thrown at it" the way I exactly want. But the less intelligent a program is, the more YOU have to be, by assessing what to expect from it and finding ways of getting it to give you something as close as possible to what you want.

iResizer is little different from any other pixel sampling program: it has its strengths, and it has its weaknesses. One such weakness is actually quite serious: it isn't, nor ever can be, 'intelligent'. As Karl's excellent before-and-after images show, the program is entirely incapable of making assessments of the kind claimed for it by Teorex, and as Teorex must surely know that, it's a matter of regret that it continues on with so silly a pretence.

Of its kind, iResizer is useful and when applied to images where significant areas of content and color are constant, its logarithm will -- like all other so-called 'object removal' logarithms -- work fairly well. Just don't expect it to be intelligent enough to 're-size' any and every image thrown at it.

The Teorex products are great at what they do, simple but effective feature set. The biggest improvement over the last time iResizer was offered (version 2.5) is transparency support. Definitely a worthwhile improvement. Thanks again Teorex and GOTD.
